Abstract

Abstract Translated from French Pont d'alimentation pouvant être soumis à des surcharges importantes formé de deux résistances identiques (1) et (1') réalisées simultanément par sérigraphie d'une couche résistante épaisse sur un même support isolant (10) dont l'épaisseur a été déterminée pour tenir lesdites surcharges, l'ajustage desdites résistances étant effectué par isolement d'une partie de la couche résistante suivant toute sa longueur. Application : en téléphonie aux ponts d'alimentation des lignes d'abonnés.
